Happening on the platform

Harry squatted down and said: “Albus Severus Potter, you was named in honor of two Hogwarts Headmasters, one of whom was a Slytherin, he was the bravest man I have ever knew.” “Sure?” the voice which was familiar said it from somewhere. But who is it? As soon as Harry turned around he saw a gray-haired man whose hair was slightly below his shoulders, wrinkles, and most importantly, a face that was damn familiar to him. And suddenly it flashed through Potter’s head: “Severus Snape.” Exactly! It is he! Harry jumped and ran into the Potions Master’s arms. Young Albus stood motionless, perplexed. Harry realized that he needed to introduce professor to his son. “Al, this is Severus Snape” Harry finally said. “The same one?!” Al asked in delight. “Do you mean “the same one”, Potter?!” Severus asked with surprise in his voice. “Sir, you are like a legend in our family! You loved grandma Lily, didn’t you? “W… what?!” This was the first time until now that the potion master blushed. “Professor, but how did you survived?” Harry asked. “Potter, I had to fake my death. Sincerely I didn’t want to, but it was necessary, if I had run away before your eyes, the Dark Lord would have found out about this, and perhaps would have killed me. I had to both motivate you and get out of my sight. “Professor…” Harry whispered almost out of tears. “Hush, my boy.” Severus carefully, as if he was afraid to scare him away, stroked Harry Potter on the back. Harry turned around and shouted to Hermione and Ron: “Come here!” Ron and his wife came running and when they saw Snape, Hermione was the first to rush to hug him: “I’m so glad!” “Me too, Granger…” Ron just shook the professor’s hand. “To be honest, I missed you, Sir.” said Weasley. “Mutually, Ronald.” Snape answered. “What are the children’s names?” “Albus Severus Potter”. Al was not taken back and decided to introduce himself.
